Application filed September 27, 1919.

T 0 all whom it may concern:

Be it known that I, GEORGE W. PAEY, a citizen of the United States, residing at Haverhill, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Jacks, of which the following is a specification.

The present invention has reference to an improved lasting jack for cobblers use.

The primary object of the invention is to produce a jack of this character which may be adjusted to various angles and degrees to suit the convenience of the workman.

A further object of the invention is to produce a ack of this character which will accommodate various sizes of lasts and effectively sustain the same on the jack.

A still further object of the invention is to produce a device of this character which shall be of a simple construction, cheap to manufacture and market and which will perform the functions for which it is devised with ease, accuracy and certainty.

Other objects and advantages will presentthemselves as the nature of the invention is better understood, reference being had to the accompanying drawings in which there is illustrated a simple and satisfactory embodiment of the invention reduced to practice, the nature of the invention being such, however, as to render the same susceptible to various changes in size, proportion and other details of construction, all of such changes falling within the scope of what is claimed.

In the drawings:

Figure 1 is a side elevation of the improvement with the last detached.

Fig. 2 is a similar view showing the last attached and the device arranged at an an gle with respect to. its support.

Fig. 3 is a sectional view approximately on the line 3-,3 of Fig. 1.

Fig. 4 is a sectional view approximately on the line 4rd of Fig. 1.

Fig. 5 is a sectional view approximately on the line 5 5 of Fig. i. i

Fig. 6 is a transverse sectional view approximately on the line 66. of Fig. 3.

The supporting member of my improvement is preferably in the nature of a hollow casting having its upper end round and its lower end provided with a depending ear.

Specification of Letters Patent.

Patented Mar. 29, 1921.

Serial No. 326,929.

The support is indicated by the numeral 10 and the car which is substantially V- shaped by the numeral 11. The car has openings adjacent to the corners thereof through which pass wood screws 12 that secure the supporting member 10 to a suitable support, such as a workmans bench. Passing through the open casting 10 a suitable distance from the top thereof is a bolt member 13. This bolt provides a pivot for a peripherally rounded head member let. The periphery of the head 14:, for a determined distance is provided with teeth 15, and these teeth are normally engaged by a dog 16 that is pivoted as at 17 in the supporting member 10 and which may be influenced by a suitable spring for retaining the same in engagement with the teeth of the head. The movement of the dog in one direction is limited by a stop block 18, and the dog is operated by a lever 19 that projects through one of the open sides of the supporting member 10. It will thus be apparent that by swinging the lever to one position the dog will be brought out of engagement with the teeth 14: and when the lever is-released the dog will then engage between the teeth of the said head. On the bolt 13 is a wing nut 20 which is designed to exert a sufficient tension between the head 14 and the supporting member, which in reality is in the nature of a casing, to hold the head against free turning on its pivot. On the head member 14 is integrally formed outstanding arms 21 which, at their outer ends are integrally formed with a sleeve 22 arranged between the said arms and bosses 23 and 24 which project beyond the outer sides of the arms. v

Passing through the bore of the sleeve and the openings in the bosses which aline with the said bore is a stem 25 that enters a boss 26 provided upon a central web plate 27 of the base 28 of the supporting member for the last. Passing through the boss 26 and engaging with the stem 25 is a binding screw 29. The head 14c is in the nature of a ring member, and has on its inner periphery a projecting finger 51, indicated by the dotted lines in Figs. 1 and. 2. The support 10 has one or both of its sides provided with inwardly projecting'radially disposed, equidistantly spaced lugs 52., and between two of those lugs the finger #51 is arranged. The lugs 52 are also indicated by the dotted lines in lfligs. 1 and 2, and the finger being in the path of contact with the said lugs,

' the swinging movement of the head on the support is thus limited.

Arising from the ends of the base 28 are brackets 30 and respectively. These brackets have alining openings therein and in the said openings are journaled the ends of an adjusting member 32. The members 32 has secured on its outer end a handle. This handle has one of its ends weighted as at 84 and its opposite end 35 provided with a hand grip 33.

The adjusting member 32 is held against longitudinal movement in any desired or preferred manner in the bearings pivoted by the brackets 30 and 31, and the said member is round in cross section and is provided at suitable points from the center thereof to the portions received in the bearings with oppositely pitched threads 36 and 3'? respectively.

The numeral 38 designates the toe block of the improvement, the same having a threaded opening in the base thereof which is engaged by the threads 36, the base of the said block 38 resting on the plate 28 of the last support. The toe block at its base has lateral extensions which are provided with downturned flanges 89 that engage with the edges of the plate 28.

The heel spindle support is indicated by the numeral 40, the same having an opening therethrough provided with threads which are pitched to be engaged by the threads 37 of the adjusting or bolt member 32. The heel spindle support 40 has its base resting upon the plate 28 and is provided with lateral extensions that are flanged downwardly as at 41 to engage with the sides or edges of the plate 28. The lever lf) may have its upper edge provided with a lug through which passes a pivoted member in the nature of a screw 68 that passes transversely through the support 10. The heel support has its upper end bifurcated and pivoted therein, as-at 42, is the heel spindle 43. This heel spindle 43 is influenced angularly in the direction of the toe block 38 through the me dium of a spring 44 carried by the heel spin dle support 40 and received in a suitable socket in the heel spindle 43. The tilting movement of the heel spindle 43 is limited by contacting engagement of a shoulder 45 formed thereon with the inner face of the member 40. On the outer and flat end of the heel spindle is an outstanding pin 46, and this pin is designed to be received in the usual aperture 47 formed on the inner face and adjacent to the heel end of a last 48.

The outer end of the toe block 38 is rounded as at 49 to receive the concaved or rounded toe portion .50 of the last 48.

revenge From the foregoing description, when taken in connection with the drawings, it will be seen that by manipulating the handle to adjust the screw member 32 the blocks 38 and 40 may be caused to travel toward or away from each other on the supporting member for the last, so that lasts of various sizes may be employed. It will be noted that the last support is revolubly arranged upon the outer end of the head member 14. It will be further noted that the head member 14 may be arranged at any desired angle and sustained at such angle so that the improve ment may be readily adapted for the convenience of the operator.

Having thus described the invention, what is claimed as new, is

1. In a device for the purpose set forth, a

support, a peripherally rounded head member journaled' in said support, said head member having peripheral teeth, a lever operated dog carried by the support engaging between said teeth for holding the head in adjusted position on the support, outstanding arms on the head, a base plate, a pivot member therefor mounted in bearings in the arms, a toe block on, the base plate having flanges engaging with thesides thereof, a heel spindle support also on the base plate having flanges engaging the sides thereof, a
